SSDs are non-invasive sensory aids that provide visual information to the blind via their existing senses. For example, using a visual-to-auditory SSD in a clinical or everyday setting, users wear a miniature video camera connected to a small computer (or smart phone) and stereo headphones. The images are converted into "soundscapes," using a predictable algorithm, allowing the user to listen to and then interpret the visual information coming from the camera.

When the researchers presented rats with new spatial environments on a computer screen, they observed long-lasting changes in the communication between nerve cells in a brain structure which is important for long-term memory (hippocampus). Thus, the researchers showed for the first time that active exploration of the environment is not necessary to obtain this effect.

Better grades, perhaps? Improved concentration? Superior driving skills? Over the past decade, many studies and news media reports have suggested that action video games such as Medal of Honor or Unreal Tournament improve a variety of perceptual and cognitive abilities. But in a new paper, psychologists critically reevaluate those claims.

The process of writing information on tiny magnetic bits one by one, as fast as possible, and with little energy consumption, represents one of the biggest hurdles in this field. Now, scientists in Europe have discovered a new method to write magnetic data that fulfills all of these requirements.

Researchers have created a noninvasive, sensor-lined cap with neural interface software that soon could be used to control computers, robotic prosthetic limbs, motorized wheelchairs and even digital avatars.

Called "BabyBeat," the system uses computer algorithms to convert video footage to pulses that represent a baby's heartbeat and skin tone. In the event that the system detects an abnormal heartbeat, an alarm sounds to awaken the baby, change its breathing pattern and alert the parents. After further testing, if BabyBeat continues to perform as expected, the students will seek to commercially produce and market the innovation.

But how can the intricate process of playing the instrument be captured digitally? A special thin film on the tailpiece has the answer. Functioning as a sensor, it converts the tension on the string into digital control signals.

In the long term the technology could be used by customers to design many different products themselves -- tailor-made to their needs and preferences. Using new digital technology the printer allows you to create your own designs on a computer and reproduce them physically in three dimensional form in chocolate.
